Currently I have upgraded version of Django 2.2 to 3.0 and suddenly getting error like below.
ImportError: cannot import name \'six\' from \'django.ut
A specified in Django 3.0 release note, django.utils.six
is removed.
In case you need it, it is advised to use pypi packages instead
In your case, jsonfield
package might be replaced by native Django's JSON Field.
Another solution would be to fork jsonfield
package yourself to solve you issue, or to make a PR on project's repo'
